(transistor output). Each I/O point is linked to separate I/O registers within the I/O Data
Store.
There are also a number of Internal I/O that can be accessed from the I/O Data Store.
These inputs can be used to interpret the status of a single module or an entire system

Battery voltage
– The battery terminal voltage displayed as an Analog value.

Loop Supply
– Monitors the +24V DC Analog Loop Supply (ALS), used to power
analog current loops and displays this as an Analog value.

Expansion Module Volts – Monitors the Supply voltage of the connected
expansion modules, displayed as an Analog value.

RSSI – Will indicate the radio signal level for the selectable address, reported as
a dB level. Note: Refer to Communication diagnostics functions and Neighbour
RSSI

Comms Fail – A selectable register can indicate a Communications fail for a
particular message transmission.
The Expansion port, allows WI-I/O-EX-1-S expansion I/O modules to be added to the
module. Expansion I/O is dynamically added to the internal I/O of the WI-I/O 9-U2 by
adding an offset to the address.
1.3 Getting Started
Most applications for the WI-I/O 9-U2 require little configuration. The WI-I/O 9-U2 has
many sophisticated features, however if you do not require these features, this section
will allow you to configure the units quickly.
First, read Chapter 2 - “Installation”, which will go through the power supply,
antenna/coax connections and any I/O connections.
Power the WI-I/O 9-U2 and make an Ethernet connection to your PC (refer to Section
4.1
“First time Configuration”)
Configure the Ethernet Interface with an IP address that is compatible with your network
or computer via the Network Configuration webpage.
Save the configuration and the WI-I/O 9-U2 module is now ready to use. For an
instruction on configuration refer to Section 4.1
“Module Configuration
